Nobody can deny that Bonnie McKee works hard for her success, and with a recent performance on Good Morning America, that success is growing more and more!

If you've been living under a rock, Bonnie is now stepping into the spotlight after years of writing hits for other artists, including Katy Perry (Teenage Dream!) and Britney! It's not easy, and Bonnie makes sure her body is fit and ready for anything that comes her way — which means lots and lots of fitness!

You gotta check out this EXCLUSIVE behind-the-scenes vid of her getting READ-Y for her GMA performance (above)! Girl was up EARLY to be 100% prepared!!

The only thing we'd change about her routine would be to get a little more sleep! Though, we totes bet it was like Christmas morning — so who could blame her this one time??

Ha!
